Devoured (2012)

Lourdes is a young woman that works at night cleaning a restaurant. All the money she made is for her son that lives in her hometown with her mother. We know very little about Lourdes son, only that he is sick and Lourdes is working every night and sending money to help her son and find a cure for his illness. Suddenly, Lourdes starts seeing visions in the restaurant where she works, in her little apartment. These visions, her evil co-workers and her son apart from her, all this stresses Lourdes out and she begins asking herself "who wants to hurt her"? Or if all of whats happening is really happening or not.—Emmankiddo
